10 Round 7.62x39 ammo pouch?

Has any one used the Molle grenade pouch for a 10 round 7.62x39 Saiga mag? I had read an old post that said they will work but I was looking on Ebay and the dimension that was given was a little short. It said 4 inches tall but my 10 round mags are 4.5 inches.

Does any one have another military ammo pouch that works well for you?
